Whether you’re pouring a concrete patio, ordering gravel for a driveway, or estimating fill dirt for landscaping, knowing the exact volume of material you need prevents costly overages and frustrating shortages. A cubic yard is a standard unit of volume in construction and landscaping, representing 27 cubic feet roughly the volume of a standard washing machine. This cubic yard calculator helps you determine the total material volume required for any project based on length, width, and depth measurements.
Contractors, landscapers, DIY homeowners, and construction professionals all rely on accurate cubic yard calculations to estimate material costs and plan deliveries. The calculator handles multiple units feet, inches, yards, meters, centimeters, and millimeters so you can work with whatever measurements you have on hand, whether you’re reading from building plans or measuring on-site.
Techraxy built this cubic yard calculator to simplify material estimation for construction and landscaping projects. Everything runs locally in your browser, so your project data stays private while you plan your next build.
Enter the length, width, and depth (or height) of the area you need to fill or excavate.
Select your preferred units for each dimension — the calculator accepts feet, inches, yards, meters, centimeters, and millimeters.
Set the number of areas you’re calculating (for multiple identical sections).
Enter the price per cubic yard and choose your currency from the dropdown menu.
Adjust the waste factor percentage to account for spillage, compaction, and material loss.
Review the summary tab for total volume and estimated cost, or switch to the detailed breakdown tab for a complete itemized view.
A cubic yard is a unit of volume equal to 27 cubic feet. The calculator determines volume using the standard geometric formula for rectangular prisms:
Volume (Cubic Yards) = (Length × Width × Depth) / 27
All dimensions are converted to feet before calculation. One cubic yard equals 27 cubic feet, 46,656 cubic inches, or approximately 0.7646 cubic meters.
The calculator automatically converts your input units to feet before applying the formula, ensuring accurate results whether you’re working in imperial or metric systems.
With Quantity: Total Volume = Volume per Area × Number of Areas
With Waste Factor: Total with Waste = Total Volume × (1 + Waste Percentage / 100)
Cost Calculation: Estimated Cost = Total Volume × Price per Cubic Yard
The waste factor accounts for material lost due to spillage, compaction, uneven surfaces, and measurement errors — a practical consideration for any real-world construction or landscaping project.
A homeowner is planning to pour a concrete patio measuring 12 feet long, 10 feet wide, and 4 inches deep. The local concrete supplier charges $120 per cubic yard. Let’s calculate how much concrete is needed.
Step 1: Identify the inputs — Length = 12 ft, Width = 10 ft, Depth = 4 in.
Step 2: Convert depth to feet — 4 inches ÷ 12 = 0.3333 feet.
Step 3: Calculate cubic feet — 12 × 10 × 0.3333 = 40 cubic feet.
Step 4: Convert to cubic yards — 40 ÷ 27 = 1.4815 cubic yards.
Step 5: Apply a 10% waste factor — 1.4815 × 1.10 = 1.6296 cubic yards.
Step 6: Calculate cost — 1.4815 × $120 = $177.78 total, or $195.55 with waste included.
The homeowner needs about 1.5 cubic yards of concrete for the patio, or 1.63 cubic yards when accounting for waste. This estimate helps with budgeting and ensures enough material is ordered for the project.
The cubic yard formula is (Length × Width × Depth) / 27, where all dimensions are in feet. This calculation gives the volume in cubic yards. For multiple areas, multiply the result by the quantity.
A standard concrete truck carries 8 to 10 cubic yards of ready-mix concrete. Some trucks can carry up to 12 cubic yards, while smaller mixers might carry 5 to 7 cubic yards. The calculator helps you determine how many truckloads your project requires.
Cubic yards measure volume in 3-foot increments (1 cubic yard = 27 cubic feet), while cubic feet measure in 1-foot increments. Cubic yards are the standard unit for bulk materials like concrete and gravel, while cubic feet are more commonly used for smaller volumes or home improvement projects.
Waste factor accounts for material lost to spillage, compaction, uneven surfaces, over-excavation, and measurement errors. For construction, 5% to 15% waste is typical depending on the project. Concrete, for example, often requires a 10% waste factor due to spillage and formwork irregularities.
Multiply cubic yards by 0.7646 to get cubic meters. For example, 5 cubic yards × 0.7646 = 3.823 cubic meters. The calculator shows both units automatically in the results.
Yes, the calculator accepts length, width, and depth in feet, inches, yards, meters, centimeters, and millimeters. All units convert automatically to feet before calculating volume.
The calculator supports USD, EUR, GBP, CAD, AUD, JPY, INR, PKR, AED, SAR, SGD, MYR, PHP, KRW, CHF, and NZD. The currency symbol updates automatically when you select a different currency.
The calculator uses the standard geometric formula with precise unit conversions. Results are accurate to four decimal places for volume and two decimal places for cost, providing sufficient precision for ordering materials.
For concrete, 10% to 15% waste is recommended due to spillage and formwork. For gravel, 10% to 15% accounts for compaction. For soil and fill, 15% to 20% allows for settlement and over-excavation. For mulch and landscaping materials, 5% to 10% is usually sufficient.
